Contaminated food, water. Contact. Bloodborne. Routes of Transmission: The first step in preventing disease is to keep the organism from entering the body. There are three primary routes of entry: Inhalation: a pathogen is usually carried on respiratory droplets in the air and enters the respiratory system; for example, colds, flu, and tuberculosis are transmitted when an infected person coughs or sneezes and spreads the microorganism through the air to others. Ingestion: the pathogen is ingested, usually via contaminated hand or food. For example, in food-borne outbreaks of Hepatitis A, the virus is shed in the feces of an infected restaurant worker who doesn\u2019t wash his/her hands properly after going to the bathroom, and then spreads the virus by handling or preparing uncooked foods or foods after cooking. Bloodborne contact: This is the focus of today\u2019s training. In the following slides, I will explain how bloodborne diseases are transmitted, which diseases are of primary concern, their incidence and prevalence, and the symptoms of these diseases.
